Khali-peeli in Iqbal’s couplets
Ishq ki tegh-e-jigar-dar uda li kis ne
Ilm ke haath mein khali hai niyam ai saqi

Tu huma ka hai shikari abhi ibtida hai teri
Nahin maslahat se khali ye jahan-e-murgh-o-mahi
Nahin maslahat se khali ye jahan-e-murgh-o-mahi
You are a hunter of the huma, your journey has only just begun; this world of birds and fish is not without its hidden purpose.
